UNLODING DEVICE RELATIVE TO UN LOADIN Gr FODDER.

Specification of Letters Patent.

Application led January 20, 1919. SerialV No. 272,083.

- and useful Improvements in an Unloading Device Relative to Unloadin FOdder, of which the following is a specification.

The primary object of this invention is to provide an improved unloadingdevice which is attached to a wagon, said device being applicable to theunloading of fodder and the like to the feeding table ofan ensilagecutter.

Another object is to provide a wagon having a conveyor forming aportion.v of the wagon bed so thatl the fodder or the like which hasbeen'lpreviously loaded on the wagon can be fed from the wagonrearwardly to a cutting or chopping device, thereby eliminating theheretofore manual unloading and piling of the fodder relative to feedingthe same into the cutter.'

Other and further objects will appear in the specification and -bespecifically pointed out in the appended claims, reference being had tothe accompanying drawings exemplifying the invention, and in which,

Figure 1 is a longitudinal section of a wagon showing this improvedunloading device applied thereto.

Figure 2 is a plan view of Fig. 1.

Figure 3 is a rear elevation showing the overlapping conveyor-in anelevated position, and serving as an end tail to the wagon.

Figure 4 is a fragmentary view showing the overlapping 'conveyor inaposition vof overlapping the feed table of the cutter, said View alsoshowing a "hand operating .mechanism for operating said conveyor, and amain conveyor.

Referring to the drawings the running gear of the wagon comprises theusual front and rear axles 1 and 2, said axles 1 and 2 being mounted ontheir respective front and rear wheels 3 and 4. Mounted on said axlesare the usual supporting yokes and 6, respectively, said yokessupporting a pair of longitudinally arranged members 7.

Mounted transversely across said members 7 are a plurality of crossmembers 8, the outer ends of said members 8 supporting the side members9. -Secured to some of the cross members 8 is a conveyor supportingframe 10, and mounted to each end of said frame are a pair of'bearings11 and 12, respectively, the bearings l1 being located adjacent thefront of the wagon bed. Mounted in t-he bearings l1 is a transverselyand horizontally arranged shaft 13, and mounted on said shaft are a pairof sprockets 14.

Mounted in the bearings 12 is a transversely and horizontally arrangedshaft 15,

and. secured to said shaft are a pair ofY sprockets 16; said sprocket-s14 and 16 are for the reception of a main conveyor 17 which comprises apair of sprocket engaging chains 18, to which are secured transverselyarranged slats 19, the upper lap ofv said conveyor being arranged on ahorizontal plane above the side members 9.-

Mounted on 'each end of the shaft 15 adj acent each of the sprockets 16is a sprocket 20, each of said sprockets 20 being co-operable with asprocket 21, said sprockets 21 being mounted on a transversely andhorizontally arranged shaft 22. Mounted on each alining pair ofsprockets 20 and 2l is `a chain 23. The shaft 22 is supported by a pairof hangers 24, each of said hangers extending from each ofthe bearings12 of the shaft l5. Said shaft 22 is also mounted in bearings which formpart of a swinging frame 25, and mounted on said frame a't the endopposite to the shaft 22 is a vhorizontally arranged shaft 2 6, havmg apair of sprockets 27 secured thereto, said sprockets beingin alinementwith a pair of sprockets 28 that are mounted on the shaft '22, each pairof alining sprockets 28 and 27, respectively, having a chain 28"1mounted thereon, and secured to said chains are a plurality of slats 29,said swingingframe 25, shafts 22 and 26, sprockets 28 and 27, and partsco-operable therewith, veyor, whic when vmounted, as shown in Fig. 1,serving as a rear end tail relative to the wagon bed, and to the frontend tail 30.

Looking towards the front of the wagon and on the left hand sideadjacent the rear is a conveyor moving mechanism, comprising a gear 31which is secured to the shaft 15,

a gear 32 inV mesh with said gear 31, said f roviding, an overlappinglconwia 1 gear being looselyr mounted on a stub shaft 33, a ratchet gear34 secured to said gear 32,

and a lever 35 loosely mounted on the shaft 33, carrying a ratchet pawl36.

the wagon bed and on the main conveyor,

the fodder is sustained in loaded position by the vertically heldswinging frame 25 and the front end tail 30, as shown inFig. 1, saidfra-me 25 being held in itsv vertical position by the tripping yoke 37which is swingingly mounted at one end vto the lower end of the swingingframe 25, the opposite end of said yoke having a notch 38 formedthereon, said notch engaging an arresting member 39 which is carried bythe rear axle 2. An engaging notch 42 is also formed in the yoke 37 forthe purpose of engaging the member 39 when the swinging conveyorfisina-horizontal position.

f After a load of fodder has been brought adjacent the cutter, the wagonis backed to a position adjacent the table 4() of thecutter, and thetripping yoke 37 is released from eni gagement with the'member 39,thereby allowing the overlapping conveyor 41 to be lowered to anapproximate horizontal position, so that the extending end thereof will-overlap the feed table 40.- 'lihe lever 35 is thenl engaged by theoperator and worked with a short reciprocating stroke, the pavvl 36engaging the teeth of the ratchet gear 34, 4

thereby turning the gears 32 and 31 and imparting motion to the mainconveyor 17, and causing the'fodder mounted thereon t-o ride ontotheoverlapping'conveyor 41, said conveyor also beingput in notion andfeeding *forward` towards the feed table 40, throughl the chains 23 andtheir respective sprockets,

and as the fodder is fed 0H the conveyor 41,

it will be deposited on the feed table 40, from members `9.l

which thecutter operator can draw the fodder from the table to theconveyor 42a of the cutter.k

ft is to be noted that the stalks of the load will be mounted `ontheconveyor 17 trans' versely thereof, so that they will be fed to thefeed table 4() in a position lengthwise thereof, said lengthwiseposition being` the proper arrangement relative to feeding the stalksinto the cutter, as said stalks are fed len thwise'onto the cutterconveyor. i

n account ofthe uppermost `lap of the conveyor being loaded on a plane.above lthe pair'of side members 9, the greater part of the weight ofthe stalks will be` borne by the upper lap of the conveyor, such anarran e-v ment assisting the feeding operation of t e stalks as the.stalks cannot be wiped from the conveyor as they would be if too muchfrictional contact were given to the stalk ends if they rested toosolidly onthe side Lawaai lin a device of this character, it is to benoted that considerable labor can be done away with relative to theunloading of fod- 'stalks in lengthwise order on the feed table.
